Cerakote for Headers. High Temperature or Extreme High Temperature

[sunny]

Came home after a good ride and measured header temps with bike still idling in garage. Sorry for the blurred images. Headers at the block (360F-370F) Heat Shields (145F-155F). This is with the Jet Hot Ceramic coating applied.

happy now?

I was happy before, and I'm still happy, thanks for asking.

Morning Guys,

These are my readings. Last Saturday 4/26/2025. I will try to describe step by step.

This is the temperature instrument used and it was basically sensing the garage temperature at noon, here in Aurora, Colorado. You can see the wire and a thermocouple.

I decided to hold it in between my fingers to sense body temp and see accuracy:

I put the thermocouple in between the exhaust and that holding shield:

Temperature reading on that location, basically "Dry Bulb":

Engine started on 12.12pm:

12.12pm 89.7F:

12.15pm idling. 356.3F

Increasing rpm's to about 1700 rpm:

I will upload more pictures using following post.

12.17 pm. 683.2F

12.19pm. 754.4F

I have a video where you can see the temperature starts to drop once idling again. So. it is not 1200F, but could be pretty high, IMHO

It'll get hotter under load.

It'll get hotter under load.

Absolutely, a full throttle acceleration through the gears will show dramatically higher temperatures than sitting in your garage (even at a high idle).
